We tend to think these activities are interchangeable from a health perspective, but are they? The surfaces that we walk on change the experience of our body and the muscles that we use.
Walking overground should be powered by the backs of our legs with our torso vertical. In order to propel us forward, our muscles generate a pushing action behind us to push the ground away.

Therefore, treadmill walking is not the same as walking overground.
